The helicopter crashed minutes after taking off from Pucallpa, about 485 miles east of Lima, on a flight to Tarapoto. It apparently tried to drop cargo as it lost power, and at least three people leapt from the aircraft, Peru's La Republica newspaper, citing witnesses, reported on Tuesday.

There were no survivors, a Peruvian judicial official said.

Local media reports initially said on Monday that those on board worked for Petrominerales Ltd, a Canadian-based oil exploration firm focused on Latin America. Petrominerales later denied those reports.

Columbia said it would work with witnesses and authorities to conduct a thorough investigation into the crash.
